BED FRAME.

Application filed .N'ovember 16, 1925, Serial No. 69,299.

My invention relates to improvements, in

v folding collapsible/bed frames of the form that are adapted tobecarried on automobiles andv the object of my invention is to 5providea collapsible bed frameof simple and substantial constructionthat is rigid and strong when extended and that is capable of beingfolded into a very small and compact package when not in use.

" Another object is to provide a'collapsible bed frame in which all ofthe parts are pivotally connected so that they may be folded in normallyhorizontal direction and to provide a bed frame which has a box orcontainer'fastened directly thereto, one part of the box being securedto the head and the other part of the box being secured to the foot ofthe bed frame.

V A further object is to provide simple and efiicient means fortightening the bed supporting member or web on the bed frame.

I accomplish these objects by devices illustrated in the accompanyingdrawings, where- I Figure 1 is a'plan View of abed frame constructed inaccordance with my invention as the same may appear when extended readyfor-use, the cover of the box at one end of-the bed frame being shown inan open position Fig.2, is a view in side elevation of the bed frame inextended'pos'ition;

Fig. 3 is a view in end elevation of the box as it may appear-when thebed frame is folded therein; 7 V

Fig.4 is a sectional view of the box substantially on broken line 4, 4of Fig. 3 showing the bed frame folded, the spring and web portion thatsupports the mattress being omitted;

Fig. 5 is a fragmentary sectional view on a larger scale showing themeans for tightening the mattress'supporting web.

Referring to the drawings, throughout which like reference numeralsindicate like parts, I show a bed frame'comprising in part two oppositeend bars'6 and 7.

connected side piece 8 that extends at right angles therefrom and at theother end with a longer rigidly connected side 9 extending The bar 6 eis provided at one end with a short'rigidly,

piece 10 and 11 respectively that extend at 55 right angles therefrom,the shorter side piece 10 of the end bar 6 being opposite the longerside piece 9 of the end bar 7 when the bed frame is assembled. 7

Two side members, formed ofparts, 12, 13, 14 and 15 serve to connect theend bars 6 and 7 and hold the same in spaced relaflion, said sidemembers being connected with the respective side pieces 8, 11, 9 and 10of the end bars by pivot bolts 16 which are normally vertical. I

The members 12 and 13 are of equal length and are pivo-tally connectedmidway betweenthe two ends of thebed by a vertical pivot bolt 17 that isoffset to the outside of said members to better facilitate the foldingofthe same. The members 14 and 15' are similarly connected by averticalpivot bolt 18. The side members are all provided at thelocations of thepivots 17 and 18 with hub portions 20 which preferably have toothed orserrated surfaces 21 in contact '13 and'14, thin flat plate portions 22,only one of which is shown, that underlie the ends of the respectivemembers 12 and 15 $5 and have notches 23 in their ends for the receptionof bolts 24 that are slidably disposed in slots 25 in the members 12 and15. When the bolts24 are moved'to ward-the ends of the slots 25 awayfrom pivots 17 and 18 the end plates 22 are released. When the sidemembers 12, '13, 14 and l5 are in the extended position and the bolts 24are moved toward the pivots 17 and 18, said bolts 24 enter the notches23 and, when the nuts are tightened thereon the members 12 and 13 on oneside and the members .14 and 15 on the other side are rigidly held inextended relation to form two rigid and non-yielding side bars.

The bed frame may be supported on legs 26 that are pivoted to the frameand arranged to be held in extended positions by folding angle braces 27A container or box for the bed is formed 105 of two halves or sections28 and 29 secured as by bolts 30 to the respective. end bars 6 and 7. Acover 31- is hinged to one of the.

box sect-ions 2S and the two sections 28 and 29 are adapted to besecured together by hooks A mattress supporting web 33 which may be.formed of flexible and easily folded cables is connected at one endwith springs 34- that are secured to end bar 7 and at the other end withother springs 35 that are connected with short cables 36 that aresecured to and adapted to be wound on a roller 37 which extendscrosswise within the end bar 6. Roller 37 is provided at one end wth aratchet wheel 38 arranged to be held against unwinding movement of theroller by a pawl 39. The outwardly protruding square end Q0 of roller 37is arranged to be engaged by a crank ll, shown dotted in Fig. 1, forturning the roller to properly tension the web 33.

lVhen the bed is extended the several parts occupy the positions shownin Figs. 1 and 2, in which position the bed frame is ready for thereception of the bed clothing. hen the bed is to be folded the nuts onbolts 2% may be loosened and said bolts 2.: moved to the ends of slots25 furthest from pivots 17 and 18 thus releasing plates The nuts onpivot bolts 1'? and 18 may then be loosened and the side bars 12, 13, 11 and 15 folded inwardly so that the side bar 12- lies adjacent to theend piece 6 and side bar 15 lies adjacent to the end bar 7 as shown inFig. at, while the side bars are being folded the web is lifted up sothat when the side bars are fully folded within the box the web may lieon top of the same. The web is omitted from the drawing in Fig. 1.Before the side bars are fully folded the legs and leg braces are foldedalong side of, or within the side bars.

The difference in length of the respective side members 8 and 9 at oneend and 10 and 11 at the other end are important in locating the pivots16 closer to or farther away from the end bars (3 and 7 so that the sidebars wil fold compactly side by side. The side bars are pivoted to foldin a horizontal plane thus malzing the folded bed frame very compact. Inpractice I lind that the bed will fold nicely within a box that is notmore than twelve inches wide and five inches deep and that may be veryconveniently carried on the running board of an automobile. The side andend bars of which the bed frame is-formed may be entirely of metal orthey may be made chiefly of wood with the pivot portions formed ofmetal.

Before folding the bed the web 33 may he slackened, if desired, byreleasing the ratchet means on the roller 37 and after opening out orextending the bed frame the ratchet means may be wound up to tighten theweb The foregoing description and accompanying drawings clearly disclosea preferred embodiment of my invention but it vill be under stood thatthis disclosure is merely illustrative and that changes may be resortedto within the scope and spirit of the following claims:

What I claim is:

In a folding bed frame of the class described, a side bar formed of twosections having overlapping ends provided with intertitting serratedhubs, one of said ends having a longitudinally extending slot, aprojecting plate portion on the other enl provided with a notch arrangedto register with said slot when said two sections are extended inprolongation of each other a pivot bolt passing through said hubs andanother bolt movable within said slot into and out of engagement withsaid notch.

in witness whereof I hereunto subscribe my name this 2lth day of October)1. 1). 192-5.
